Instructions on package were confusingBy Charleson 6/12/2013

I got this from a friend that had taken down his tank. I am overall satisfied with the product itself, but the instructions were confusing and I believe i used way too much after the initial period. I got some clarity on it with the calculator. My pump went up on me for a couple days and i started noticing algae growth almost instantly. Got a new pump and did a water change and the GFO did the rest.

Good quality GFOBy Billon 6/7/2013

This GFO works well and is very cost efficient way of removing PO4 in any aquarium. No problems does exactly what it is supposed to do.
I do find that it has more fines to be rinsed than some higher quality GFO (RowaPhos).

effective and good priceBy Mikeon 6/2/2013

Used regularly it has transformed my reef from an algae jungle to a coral jungle!

With the use of the BRS GFO I have removed just about all my algae problems in my tank.

Although I find the need to flush BRS gfo more than others I have used in the past, the cost difference more than makes up. Another solid product out of the BRS team!

Have been using for about 3 weeks so far with no change in my phosphate level. Doing water changes also. Need more time to evaluate not sure about recommending yet. Phos Ban maybe better.

Having started with SW in the dark ages and then coming back to it alot has changed and gfo is certainly a great product. I had been battling dino's for a few weeks. Within 24 hrs of starting with gfo I noticed a immediate reduction in dinos to almost complete elimination in less than a week.
